In 1897 Vizentini became director of the Grand Théâtre de Lyon, where he staged and conducted the first French performance of Wagner's Die Meistersinger.

He also wrote two cantatas performed at the Vaudeville and the Porte-Saint-Martin, and music for several plays including Nos ancêtres, Cadio, Patrie, Le Bossu, etc.
